Thereasonabledesignofbeam专业英语论文.docThe reasonable design of beam
Abstract: Beam is an important supporting member in the building, Beam quality,has important influence on safety and durability of the building, Therefore, in the amount of design, should consider the factors,carries on the reasonable design.
There are many factors that can influence the beam quality,including beam to support position,beam under the load,on the surface shape of the beam, and the shape of the beam…
Beam design is discussed in this paper discussed the basis, proposes and explains the selecting of beam according to in trying to force form, choose according to stress distribution of cross section shape and size, according to the moment of inertia Iz choice of beam cross section shapes and sizes,choose according to beam deflection formula of the beam in the form of a few problems,such as.
Key words beam; Design; Stiffness; Cross section
Introduce: According to the requirements of the beam intensity and stiffness,
combined with the practical rational design of beams, is the research task of material mechanics. In beam design is the basic question of how to guarantee under the premise of meet the requirements of strength,stiffness and stability,in the most economic price,the rational design of beams,which meet the requirements of practical and economic.
First: discussed on the basis of beam design
Beam design, on the practical req
